It may seem like the simplest of tasks but, according to at least one medical professional, we are doing it wrong.
Most antiperspirants active ingredient is aluminum chloride. Aluminum particles are taken up by cells in the sweat glands, causing them to swell and close up so they no longer release sweat. (Some experts warn we should look for deodorants that don’t contain aluminum.)
Meanwhile, Doctor Dawn Harper, recommends we apply antiperspirant at night so it has time to ‘set’ in the pores during sleep. Drying is such an important step that it is best to avoid applying to damp skin (as in not right after we shower.)
Dr. Harper adds, less is more, with a good quality deodorant it only needs to be applied twice a week.
She suggests: 'Apply 2 strokes up and 2 strokes down to each armpit. You should only need to do this once or twice a week.'
